Both great! Juka will waterfall a bit better and overall, has a bit more athority in 3D. The su29 will have the edge in precision flying. It turns true, and tracks a bit better than the Juka. Both are great, and both have strong/weak points.

Jholen, yeah, I haven't flown my SU-29 yet but it's very similar to the Yak. I will get some time with it any day now.

I agree with Michael on the Yak/Su29 being great 3D and precision balance, and also that the Juka is the 3D king. If you're a non-expert, the dEPPron fusion planes are a great choice as the thicker fuse slows 'em down more and it's ridiculously easy to hover. And with the EPP you will fly lower and more aggressive 3D.
